Stem Cell Eye Treatments
Blind patients suffering from a type of eye disease that strikes in childhood will become the second group of people in the world to receive stem cells left over from fertility treatment.
The US Food and Drug Administration (FDA) has given the go-ahead for the controversial transplant of embryonic stem cells into the eyes of patients with Stargardt's macular degeneration, where the light-sensitive retina cells at the back of eye are destroyed. The announcement follows the first injection of embryonic stem cells into a patient in the US who is partially paralysed as a result of a spinal cord injury. Last October, a US biotechnology company, Geron, announced the start of the first clinical trial of embryonic stem cells with the hope of repairing damaged nerves.

- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
